This application has been filed under 35 USC 371 as a national Stage Application of PCT/EP95/01933, filed May 22, 1995.

The invention relates to novel heterocyclic imino derivatives, several processes for preparing them and their use for controlling pests.

It is known that various substituted alkoximino- and alkoxymethyleneacetamides have fungicidal properties (compare, for example, EP-A 398 692, EP-A 468 775, DE-A 40 30 038 and WO-A 92/13 830).

However, the efficacy of these previously disclosed compounds is not entirely satisfactory in all areas of application, especially at low application rates.

Very good tolerability of the active substances by plants at the concentrations necessary to control plant diseases allow treatment of the above-ground parts of plants, of plant and seed materials and of the soil.

In this connection, the active substances according to the invention can be used particularly successfully for controlling diseases in fruit and vegetable crops such as, for example, against Podosphaera species, or for controlling diseases of rice, such as, for example, against Pyricularia oryzae.

The active substances can be converted into customary formulations depending on their respective physical and/or chemical properties, such as solutions, emulsions, suspensions, powders, foams, pastes, granules, aerosols, microencapsulations in polymeric materials and in coating compositions for seeds, and ULV cooled and warm fogging formulations.

These formulations are produced in a known manner, for example by mixing the active substances with extenders, that is to say liquid solvents, liquefied gases which are under pressure and/or solid carriers, where appropriate using surface-active agents, that is to say emulsifiers and/or dispersants and/or foam-generating agents. In the event that water is used as extender it is possible, for example, also to use organic solvents as auxiliary solvents. Suitable liquid solvents are essentially: aromatic compounds such as xylene, toluene, alkylnaphthalenes, chlorinated aromatic compounds or chlorinated aliphatic hydrocarbons, such as chlorobenzenes, chloroethylenes, or methylene chloride, aliphatic hydrocarbons such as cyclohexane or paraffins, for example petroleum fractions, alcohols such as butanol or glycol, and their ethers and esters, ketones such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, highly polar solvents such as dimethyl formamide or dimethyl sulphoxide, and water; liquefied gaseous extenders or carriers meaning liquids which are gaseous at normal temperature and under atmospheric pressure, for example aerosol propellant gases such as halogenated hydrocarbons, and butane, propane, nitrogen and carbon dioxide; suitable solid carriers are: for example natural rock powders such as kaolins, aluminas, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth and synthetic rock powders such as highly disperse silica, aluminium oxide and silicates; suitable solid carriers for granules are: for example crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite, dolomite and synthetic granules of inorganic and organic powders, and granules from organic materials such as sawdust, coconut shells, corn stalks and tobacco stalks; suitable emulsifiers and/or foam-generating agents are: for example non-ionic and anionic emulsifiers such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkylsulphonates, alkyl sulphates, arylsulphonates and protein hydrolysates; suitable dispersants are: for example lignin sulphite waste liquors and methylcellulose.

It is possible to use in the formulations adhesives such as carboxymethylcellulose, natural and synthetic, powdered, granular or latex-like polymers such as gum arabic, polyvinyl alcohol, polyvinyl acetate, and natural phospholipids such as cephalins and lecithins and synthetic phospholipids. Other possible additives are mineral and vegetable oils.

It is possible to use colouring agents such as inorganic pigments, for example iron oxide, titanium oxide, Prussian blue and organic colouring agents such as alizarin, azo and metal phthalocyanine dyes and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.

The formulations generally contain between 0.1 and 95% by weight of active substance, preferably between 0.5 and 90%.

The active substances according to the invention can be used as such or in their formulations also mixed with known fimgicides, bactericides, acaricides, nematicides or insecticides in order thus, for example, to widen the spectrum of action or prevent development of resistance.

They are used in the customary manner, for example by watering, spraying, atomizing, scattering, dusting, foaming, brushing on and the like.

23.1 g (0.1 mol) of 2-(2,6-dichlorophenyl)-imino-oxazolidine (compare DE-OS (German Published Specification) 19 63 192) were introduced into 150 ml of tetrahydrofuran, 13.4 g (0.12 mol) of potassium tert-butoxide were added, the mixture was stirred at room temperature for 30 minutes, then 21.8 g (0.14 ml) of methyl bromoacetate were added and the mixture was stirred at room temperature for 5 hours.

The suspension was subsequently poured into 500 ml of water and extracted 3 times with 80 ml of methylene chloride each time, and the organic phase was dried over sodium sulphate and concentrated in vacuo. Chromatography on silica gel with ether as mobile phase then provided a colourless oil.

16.9 g (56% of theory) of N-methoxycarbonylmethyl-2-(2,6-dichlorophenyl)-imino-oxazolidine are obtained.

Preparation of the starting materials of the formula (VIII) Example (VIII-1) ##STR193##

5.8 g (25 mmol) of 2-(3-trifluoromethylphenyl)-imino-oxazolidine (compare, for example, DE-OS (German Published Specification) 19 63 192) were introduced into 60 ml of tetrahydrofuran, 5.5 g (40 mmol) of potassium carbonate were added, 3.6 g (30 mmol) of methyl oxalyl chloride in 40 ml of tetrahydrofuran were added dropwise at 0° C., and the mixture was stirred at room temperature for 72 h.

The suspension was then added to 250 ml of water and extracted 3 times with 70 ml of ethyl acetate each time, and the organic extracts were dried over sodium sulphate and concentrated in vacuo. The residue was subsequently stirred in 30 ml of n-pentane, and the resulting solid was filtered off and dried.

2.1 g (26% of theory) of the abovementioned compound, which decomposes on heating to 80° C., are obtained.

¹ H-NMR (CDCl₃): δ=3.36 (s, 3H, OCH₃), 3.83 (t, 2H, CH₂), 3.97 (t, 2H, CH₂), 7.74-7.90 (m, 4H, Ar--H).

USE EXAMPLES Example A

Podosphaera test (apple)/protective

Solvent: 4.7 parts by weight of acetone

Emulsifier: 0.3 part by weight of alkyl-aryl-polyglycol ether

To prepare an expedient active substance preparation, 1 part by weight of active substance is mixed with the stated amounts of solvent and emulsifier, and the concentrate is diluted with water to the required concentration.

To test for protective activity, young plants are sprayed with an active substance preparation until dripping wet. After the spray deposit has dried on, the plants are inoculated with conidia of Podosphaera leucotricha, which is the cause of apple mildew.

The plants are then placed in a glass house at 23 and at a relative humidity of about 70%.

Evaluation takes place 10 days after the inoculation.

In this test, for example the compound of Preparation Example 9 shows an efficacy of 86% at an active substance concentration of 10 ppm.
